Two justices for the highest court in Massachusetts have asked state lawmakers to change a tough wiretap law to enable police to investigate and prosecute the hundreds of shootings and killings committed by street gangs. Supreme Judicial Court Justices Ralph Gants and Judith Cowin made the call Friday in an opinion supporting a ruling barring secretly-recorded evidence from being used against a man who admitted to a 2007 drive-by killing in Brockton.

Federal immigration officials say a three-month operation in Massachusetts, Maine, Connecticut and Rhode Island has led to the arrest 47 of people suspected of being gang members or having ties to gangs.
